Troubleshooting • Re: RPi4B reduced memory

Oops, my apologies for this thread. I've just realised that 768 is 256 * 3 and found a line in syslog that says 0x30000000 upwards will be ignored because I don't have HIGHMEM set in the kernel. "I thought that highmem was only for memory > 4GB. I'll fix my kernel and try again.
Troubleshooting 101: Test with a standard OS and kernel.
Fault reporting 101: Admit to using non-standard OS/kernel, preferably list their versions, even if they are standard.
